get "/", PageController, :index -
get is a Phoenix macro which expands out to define one clause of the match/5 function. It corresponds to the HTTP verb GET. Similar macros exist for other HTTP verbs including POST, PUT, PATCH, DELETE, OPTIONS, CONNECT, TRACE and HEAD.
The first argument to these macros is the path. Here, it is the root of the application, /. The next two arguments are the controller and action we want to have handle this request. These macros may also take other options, which we will see throughout the rest of this guide.
If this were the only route in our router module, the clause of the match/5 function would look like this after the macro is expanded:
def match(:get, "/", PageController, :index, )
